Is the indoor air quality at universities and colleges impacting student health and academic performance? Unfortunately, there’s a good chance that the answer is “yes.” A big reason for this is the widespread presence of mold in classrooms and residence halls.
What are the health risks? And how can campus leadership and facility experts take action to prevent this?
Many universities were not incredibly healthy environments for human beings before the pandemic. In too many places, the norm was: older buildings, unhealthy air quality, pest issues, and mold. According to CDC Director Rochelle Walensky, schools should improve ventilation “to the extent possible,” by opening windows and doors if they can do that safely.”
The guidelines also urge schools to consider upgrading ventilation systems in order to deliver more clean air and dilute contaminants. Dr. Walensky says that improving HVAC systems would help with other public needs beyond COVID-19, such as reducing asthma and reducing exposure to mold issues.
Here’s the thing about mold: it requires oxygen, water, and a source of food to grow. There are molds that can grow on almost anything, including wood, paper, carpet, foods, and insulation. Because of this, controlling moisture is the key to managing mold.
Mold grows when airborne mold spores land on a damp “food source” and begin digesting it in order to survive. The water required for mold growth can enter campus buildings and portable classrooms through leaky roofs, pipes, windows, foundations, and other structural openings. Water may also enter classrooms or residence halls due to floods, poor drainage, or mis-directed sprinklers. Mold can even enter via biomaterial (food or fluids)transported in by faculty or students.
Classrooms, offices, and building corridors often harbor mold spores and dust mites, as do ventilation systems. Moisture problems in universities can also result from scheduled maintenance activities or conditions during spring or winter breaks such as:
Mold in residence halls and classrooms affects staff and students alike, particularly those with respiratory problems. Mold can lead to a range of adverse health effects, including:
Less common symptoms include fever, vomiting, nausea, nosebleeds, dizziness, memory loss, diarrhea or constipation, and changes in behavior. Not everyone has the same symptoms, and some are not bothered at all.
Other symptoms may be related to exposure to chemicals produced by molds – including the volatile compounds that cause moldy odors and chemicals known as mycotoxins – or fungicides and other chemicals that are applied to try to kill mold.
If a community member has allergies, especially to mold, you should:
An important way to start mold remediation at universities is to reduce indoor humidity (to 40-60%) by:
How can you know whether humidity and other conditions are creating mold growth? You need to monitor your air.
This requires a device that can proactively detect what is in your air, and alert you to any issues that arise.
The way to control indoor mold growth is to control moisture. If mold is a problem on campus, you must clean up the mold and eliminate sources of moisture. Delaying repairs or cutting back maintenance makes mold problems worse. Many universities and colleges have mold problems because of poor construction, or because they are tightly sealed and poorly ventilated, which prevents moisture from escaping.
Campus leadership should help monitor schools for moisture, water damage, and resulting mold problems.
In the quest to reduce mold in schools, real-time air monitoring is key. By tracking VOC levels, PM2.5 particles in the air, temperature and humidity levels, you can receive a warning when the conditions are present that cause mold to grow, and prevent it at the outset. Students and faculty should advocate for schools to apply IAQ monitoring and share the data to show mitigation and improvement.

If you are concerned about your university, let administrators knowhow important IAQ is, how easy it is to improve it with the right insights, and have them reach out via this form.
House mold is the bane of homeowners. A silent, creeping enemy, it isn’t only ugly – it can harm your health. Based on reports from EPA and the Berkeley National Laboratory, about 4.6 million cases of asthma in the US can be attributed to house mold exposure. And now that many of us are spending an unprecedented amount of time at home, mold growth is a more pressing concern than ever.
It’s critical to provide students with a safe and comfortable environment that will enable them to learn and grow. Unfortunately, one of the most important factors that affect students’ ability to succeed is often overlooked, even though it’s hiding in plain sight: the quality of air in schools.
One of the biggest challenges you can face as a renter is how to make your apartment feel like your own. It isn’t easy decorating and expressing your personal style while having to draw within the lines of the long list of rules on your lease. If you’ve gotten creative and figured out a few ways to change up the apartment’s aesthetic to make it feel like more like your apartment, you’re on the right track! There’s another way you can take control of your apartment like any homeowner beyond decorating, and it involves how healthy you choose to make your space.
